Yes, a femur rod CAN prevent enlistment in the US Military.
I cannot say that it will automatically disqualify you from every branch all the time, but in my specific case I was denied a waiver by the Marine Corps in December 2010.
I applied to enlist in the Marine Reserves. I have full range of motion with the leg in question, the hardware (1 rod, 3 pins) is stable and has been since implanted 8 years ago. I have no pain. The waiver denial is permanent unless the underlying condition is remedied (i.e., I were to have the rod/pins surgically removed). At that point I could resubmit a waiver though there are no guarantees the outcome would be any different.
The system for medical waivers is very opaque even to recruiters and as a civilian who has never worked at BUMED (the waiver authority for the Marines), I cannot tell you the reasons some people get waivers and some don't. I'm positive that there are people in the Marines today who joined with a rod in their leg, based simply on the fact that one can even apply for a waiver for it.
Just remember that if your waiver request is rejected, it is not because a particular service feels you are not worthy or that you aren't capable of contributing - it is a decision based on your specific medical condition and how it could affect you in critical situations. In my case I was otherwise well-qualified and very motivated to earn the title but neither of these changes the medical facts of my case. Also, take heart in the fact that rejections are service specific: if the Army won't waiver a condition, there is a chance another branch will.
PS - If your waiver is rejected, show some class about it. Yes it sucks, but your recruiter didn't do it to you and the enlisted men and women who have earned the privilege of serving didn't do it either. Unfortunately the most venomous anti-military tripe you encounter often comes from people who wanted to serve and were denied.
The rod is inside or alongside your femur, but the screws are in the knee end of the femur, not the knee itself.
Steel rod can be stay inside your femur till end of your life unless you face any accident repeatedly, because I have rod in my leg after breaking of femur since 17 years and I don't feel any incomfortability.
Yes but be very mindful of collisions and hard falls
Coat rod and hooks with car wax.
Almost certainly. Most orthopaedic metalwork is compatible with MRI scanners and large items such as a rod in the femur don't pose a particular problem as they are fixed in place and won't move. It would be wise to check with the MRI staff and/or the orthopaedic surgeons, however.
The rod that is used to prevent forward or rearward movement of the u-beam on a twin u-beam front suspension is called the tie rod. A tie rod is part of the steering mechanism.
I am going to guess that you don't live in north America A femur is a portion of a human leg and as this is in automotive section you are describing an automotive part. Please include make model year and what the manufacturer calls the part in your re-post of the question.
to prevent back and forward i-beam movement
The electricity from lightning will follow a wire from the lightning rod to the ground.
Yes. A tanning bed is simply an array of UV-emitting fluorescent light bulbs, and a titanium rod will not affect any aspect of the tanning process, however tanning is never a completely safe practice.
Typically for a broken femur, they will do surgery and put in a rod and pins, if they do a cast, it is a body cast
A lightning rod is a metal rod placed in various structures to prevent lightning from striking them. It attracts the lightning to itself, and it is channeled into the ground.
